Does anybody know if anyone makes Magna style round to square butt conversion grips for J-frame Smiths? I'm looking for a set for my round butt M36. The round butts are just too small for me to hold on to reliably when shooting hot +P rounds, but I also want to keep it original looking so rubber or target stocks are out of the picture. Basically I want it to look and function like a stock square butt Model 36. Thanks in advance for any leads.
